问题：kwin-libs安装失败。kwin-libs-5.15.8.15-1.an8.x86_64依赖的许多包，默认的yum源中没有。

$ sudo yum install -y yum-utils
$ sudo yum-config-manager --enable DDE
$ sudo yum-config-manager --enable Plus
$ sudo yum clean all && yum makecache
$ sudo yum groupinstall -y dde

处理kwin-libs安装问题

经过在网上的一番搜索，发现https://pkgs.org/上有适合“CentOS 8/EPEL x86_64”的安装包。查看上面的安装方法后，觉得可以自行添加yum源进行安装。下面介绍kwin-libs的yum源配置及DDE安装过程。

安装DDE

1. 安装yum-utils，启用DDE、Plus两个yum源

$ sudo yum install -y yum-utils
$ sudo yum-config-manager --enable DDE
$ sudo yum-config-manager --enable Plus

2. 配置kwin-libs的yum源

$ vim myrepo.repo
[myrepo_01]
name=myrepo_01
baseurl=https://download-ib01.fedoraproject.org/pub/epel/8/Everything/x86_64/
enabled=1
gpgcheck=0

3. 清除及重新生成yum缓存

$ sudo yum clean all && yum makecache

4. 安装kwin-libs

$ sudo yum install -y kwin-libs

5. 安装DDE

$ sudo yum groupinstall -y dde
